a varigated shingled roof to show alot of texture. I would do a natural wood tone garage door.

I would make it black.

I ,ove black windows but for sure not all those grids everywhere . Start by getting a diffent garage door that has maybe a simple row of windows at the top and no other gris pattern.The one you show does not suit the house . I dislike a ton of window grids and for sure with brick The windows Beverly shows below in the main part of the home are perfect not the ones on the upper storey . Too much of a thing is always too much.

Filling in the one gable end with siding seems out of place. Keep it all brick.
